1. Traverse an array and merge the objects in the array if the values of the objects in the array are equal
//
var a = [
{
date:"2018-7-24",
value:2
},
{
date:"2018-7-24",
value:5
},
{
date:"2018-7-25",
value:5
},
{
date:"2018-7-25",
value:5
},
]
//
res = [
{
date:"2018-7-24",
value:7
},
{
date:"2018-7-25",
value:10
},
]
if you want to break your head, you still don"t know if anyone has a better way. Thank you very much!
